Answer:
1 container and 14 cups
Step-by-step explanation:
We know that 1 quart = 4 cups
therefore, 12 quart = 48 cups
each container has 34 cups
so one container would be full and remaining 48-34 =14 cups can be filled in another container.
Answer:
This is not a triangle
Step-by-step explanation:
If you use the triangle inequality theorem you can reach your answer.
The theorem states that if you add the length of any 2 sides together, you will have a length greater than the length of the other side. Using this method we can easily see that 7+6=13 which is less than 21. Meaning this is not a triangle
The correct answer is 21 and 9. 21+9=30 and 21-9=12. Hope this helps.
